What is the power output of the qi pad? The USB ports claim to be 1 and 2.1 amps so is the pad going to be about 1 amp as usual for qi pads?

I am not exactly sure what the output is, anecdotally though it charges our nexus 5s in about 2 hours on the pad and in about 45 min on the USB port. Other reviewers are correct about watching your placement of the phone. The pad will make a little chirrup tone when the phone is placed correctly, but if you bump it off even slightly you will only know it has stopped charging because the red LED goes out. This takes around a min or so to go out so I tend to check it a couple of min after I start charging my phone . I have not pushed the charger to the limits yet, the most I have needed so far is 3 full charges in a row without recharging and it was still going strong.

I'm not sure what the output is but I do use it for my iPad. If I plug not in before I go to bed its fully charged by morning.

I use it with one and an iPad without problems. This is 2.1 amps per port which is more than needed. However, if you are only using phones and no tablets, you are paying for more than you need.

my ipad charger says 5.4v - 2.4amp. this unit has two USB's one is 1amp and one is 2.1amp output.

A USB port uses a max 500ma of +5vdc power = 2.5 watts. Thanks for using AnswerParty!

Yes USB uses 5V 1A. To Charge tablets, iPad, etc., sometimes make sure that the output is 5V 2.1 amp, higher the amperage, better charging time.

The maximum output current of this USB port is 1500mA (I know because I measured it) although Monster web site says 1000mA. So it will charge up your iPad slowly even if the iPad is on.

As I understand, the higher side output is 2.1 amps at 5 volts. I believe most USB ports on computers put out 0.5 - 0.9 amps. 2.1 amps will charge devices faster. I'd recommend contacting Mediabridge directly - http://www.mediabridgeproducts.com/store/pc/home.asp (856) 216-8222. They were most helpful when I was deciding to buy.

It has 4 usb ports, but only outputs 24W of power. I had trouble charging 2 android tablets at the same time when the batteries were really low. Look at your chargers that came with you laptop and gopro and see what wattage they are.

USB 2.0 can go much further, and the power rating has been listed everywhere from 7 to 14db, I would estimate it's around 10 to 12. I get full signal off a hotel that is 1/8th of a mile away. And I can connect to several that are a bit further out. It isn't super high powered, but it does an excellent job of beefing up the signal. I got 1 to 2 bars without it, full with it, and that is inside my home, outside I can find several wifi hotspots I can't even see without it.

I've tried to judge the charging distance between the pad and device, I've found that a rough maximum of 4mm is about as far as you can go from the power source before charging doesn't work.

MANUFACTURER RESPONSE: Thanks for asking! 2.5A is the total power available from the power supply- NOT the amount of power available to ANY ports. To say that another way, you would have 625mA (.625A) power per port max when using all 4 ports. The max current draw for a device complying with the BC 1.1 specification from any given port is 1500mA (1.5A). Please note this full current draw would be available to only one device at a time. When charging 2 devices simultaneously, we would expect charging at a max rate of around ~1250mA (~1.25A)- assuming no current is required by devices in the other two ports. Sorry we can't offer a more clear explanation here- USB charging is really a complex topic where devices from different manufacturers have very different behaviors. To top that off, many devices actually negotiate with the host PC to determine what rate to charge at, so behaviors on these will vary depending on whether a host PC is on and awake versus when there is no host PC or when the PC is sleeping.

I'm actually using a spare one for that function now. HOWEVER, it will only charge items at the USB limit of 500mA per port. Most true chargers are capable of 700mA to 1000mA depending on the device.

I don't know the power as I haven't a means to test it, but I'd assume that 500mA is what they provide. I do know that they provide power and I use thme to charge usb speakers, a small helicopter, usb headset and many other devices as well as a Nook HD+ and IPad all at the same time. I also use it as a hub when I'm on my desktop computer (usually on the laptop).

2.1 amps shared; it can produce the full 2.1 amps only if 1 port is being used. 1 amp per USB port can be used if both ports are in use.

This unit has a USB outlet capable of providing 2.1 amps. All you need is a cable with a USB A male plug on one end and a plug that will fit your device on the other.

The first answer is a bit off, because they did not consider the step down from the power supply at 12V to the USB slots at 5V. The power supply is 5A at 12V, or 60 watts. The 9 USB slots provide .9A each at 5V, for a total of 36.5 watts. Add the 2.1A at 5V for the charging slot, and you have a total of 36.5 + 10.5 = 47 watts. This is within the capability of the power supply. So, you should be able to deliver the full rated power to all of the slots simultaneously.
